1,2-Epoxy-1,2,7,7',8,8',11',12'-octahydro-psi,psi-carotene belongs to the class of organic compounds known as sesquaterpenoids. These are terpenoids with at least 7 consecutive isoprene units. 1,2-Epoxy-1,2,7,7',8,8',11',12'-octahydro-psi,psi-carotene is considered to be a practically insoluble (in water) and relatively neutral molecule. Within the cell, 1,2-epoxy-1,2,7,7',8,8',11',12'-octahydro-psi,psi-carotene is primarily located in the membrane (predicted from logP) and cytoplasm. Outside of the human body, 1,2-epoxy-1,2,7,7',8,8',11',12'-octahydro-psi,psi-carotene can be found in garden tomato. This makes 1,2-epoxy-1,2,7,7',8,8',11',12'-octahydro-psi,psi-carotene a potential biomarker for the consumption of this food product.
